flipping of earth's poles

Magnetic pole flipping has never been observed. We would expect to see it if it were real.

And your physical display is right in the seafloor. But of course you will troll that away.

The seafloor can only record pole position not a flip. Show me where I am wrong or how it could record flip.

No, the flipping hasn't been observed because the last one occurred tens of thousands of years ago.

But the records on the sea floor can't be disputed.

Now stop trolling.

Thanks, Rich

THE RECORD OF THE REVERSALS OF THE MAGNETIC FIELD OF THE EARTH!

Go away, troll.

When a parallel RC circuit is ringing, when does the magnetic field go sideways?

Thanks, Rich

You are claiming more than you have achieved. You did not demonstrate any flip measured at the seafloor. And the phenomenon has never been observed ever at any scale.

A parallel RC circuit is a series RC circuit with the ends connected.

There is no electric curcuit based magnetism in the Earth's core. Rather it is iron based. Its orientation can change but it cannot magnetically degenerate and thus reverse the poles.

How do you measure a reversal? I don't think you can. Prove that you can.

You could measure a change in orientation but not a reversal.

The temperature at the earth's core is way higher than the ferromagnetic critical temperature of iron. Other people here refer to the Curie temperature, in ignorance of the fact that Curie temperature has nothing to do with ferromagnetism. However, I understand their point. Ferromagnetism can't exist above the ferromagnetic critical temperature. The critical temperature of iron is a couple of hundred degrees Centigrade. The temperature of iron is more than 5000 degrees Centigrade. Obviously, the iron in the center of the earth is no more magnetic than a lump of lead. This is independent of whether the iron is in solid or liquid form. Iron in the center of the earth is too hot to be magnetized. However, the iron in the center of the earth is not too hot to be an electrical conductor. Therefore, it supports electrical currents. Any chemical or frictional force that generates a voltage in the center of the earth has to generate an electric current. This electrical current has to generate a magnetic field. The "earth- dynamo" model implies that the forces generating the electrical current are related to the spin of the earth, and to the convection currents at the core. Whether this model is true or not is irrelevant to my main point. The earth dynamo model has nothing to do with permanent magnets. The properties of permanent magnets can not logically falsify the earth-dynamo model. Your refrigerator magnet is irrelevant to the validity of the model. The same argument goes for the sun. Of course, the sun is made mostly of hydrogen and helium. However, it has vapors of every element including iron. The sun actually has a surprising amount of iron vapor, as shown by the absorption lines of iron. However, the temperature of the sun is still much higher than the ferromagnetic temperature of iron. Therefore, no one has suggested that the magnetic field of the sun is due to iron. Ironically, iron is STILL an electrical conductor in the sun since it is ionized vapor |:-) Your argument concerning the refrigerator magnet are just as invalid on the sun as they are on the earth. Your magnet doesn't flip because the material in it is below the ferromagnetic critical temperature of whatever the material is. It is probably iron in your magnet, though it could be other ferromagnetic materials materials (cobalt, nickel, magnetite, etc.). As long as the temperature is below the ferromagnetic critical temperature, the material will tend to hold on to its magnetization. However, it can't at high temperatures. Note that gases on the sun are all electrical conductors. This is because the gases on the sun are all ionized. The gases on the sun are plasmas, which are always conductors. So the sun supports electric currents, generated by motions of this conductor. The same thing applies to the earth, but slower.

I don't know what a "parallel" RC circuit is. Furthermore, the earth isn't supposed to be like an RC circuit. It is more like an LRC circuit. In an LR circuit, the largest magnetic field is in the inductor (also called a choke by electricians). The magnetic field in the inductor resists changes in the electric current. This can also create ringing, similar to an RC circuit. The inductor is a coil of wire. The coil of wire can but does not have to have a soft ferromagnetic core. The smaller inductors don't have a ferromagnetic core at all. A soft ferromagnetic core increases the magnetic field, but can't store the magnetic field very long without an electric current. Many circuits have resistances, inductors and capacitances, which can be modeled as an LRC circuit. LRC circuits also ring. The magnetic field in the inductor periodically vanishes. The energy is then stored by the electrical field of the capacitor. Note that the wires also have a capacitance, as there is an electric field on the surface of the wire in the case of alternating current. The analogy for the earth would be when the magnetic field vanishes, the energy is stored in the electric field on the "surface" of the iron core. This means that when the magnetic field vanishes, the electric current in the core of the earth increases. So imagine that the vanishing electric field induces an electric current at the surface of this molten core. The magnetic field never goes "sideways," What goes sideways is the electric field at the surface of the core.

The magnetic field can collapse to nothing if the energy goes into an electric field, or into an electric current. The surface of the iron core has an electric field and by ohms law, and electric current. When the magnetic field has vanished, the current has already reverse direction. The magnetic field builds in the opposite direction. When the magnetic field is at a peak, the curent has vanished. There is nothing to support the magnetic field, so it starts to vanish. A changing magnetic field is always associated with a changing electric current. The changing magnetic field can generate and even reverse an electric current. A changing electric current can generate and even reverse a magnetic field. Ding dong, its called ringing.

Agreed

Ummm...

Actually, it seems that the last reversal was about 12,000 years ago. It is called the Gothenburg Reversal because the original data came from that time. It was preceded by the Mono Lake reversal at about 23,000 years ago. Before that we had the Lake Mungo reversal at about 33,500 years ago. That was preceded by the Laschamp Reversal at about 47,000 years ago.

I wonder if anyone sees a possible pattern here?

These reversals also *seem* to correlate with mass extinctions AND global Ice Ages. (After Gothenburg, there are no further records of Mammoths, Giant Sloths, Sabre Tooth Cats, Dire Wolves and many others. The last Clovis points are found in layers just preceding that reversal.)

Here is a link to a nice article from UC San Diego regarding dating: and reversals...

In an LC circuit that is ringing, the magnetic field of the inductor (L) oscillates. The energy goes into the electric field of the capacitor (C). The iron in the center of the earth is an electrical conductor. There is an electric field on the surface of the iron core which provides the capacitance, C. There is a magnetic field aligned with the poles that provides the inductance, L. There is the spin of the earth and convection currents that orient the fields relative to the north and south pole. I strongly recommend that you read up on LC circuits. You will find electromagnetic theory is fascinating, with or without your meds |:-)

Since you seem unable to comprehend English, here's a picture:

Each time it changes from black to white and vice versa, the direction of Earth's magnetic field has changed. It's recorded in the magnetic basalt issuing from the mid-atlantic ridge.

But, apparently, like the Warmingists, your faith is immune to facts.

Please stop trolling.

'Scuse the typo - I meant LC. That's an inductor in parallel with a capacitor.

Who told you that the Earth's core is solid? You need to go back to school.

Come back after you've learned something other than fallacies.

Good Luck! Rich
